ArcLength and Sector Area

Find the length of the arc.

Recall: $Length=\frac{\theta}{360}\left(2\pi r\right)$  

•  $10\pi\ cm$  

•  $150\pi\ cm$  

•  $5\pi\ cm$  

•  $75\pi\ cm$  

• None of the above

Find the area of the sector with a radius of 3m and measure of 150 degrees. Recall:  $Area\ =\ \frac{\theta}{360}\left(\pi r^2\right)$  

•  $3.75\pi\ m^2$  

•  $7.5\pi\ m^2$  

•  $2.5\pi\ m^2$  

•  $1.25\pi\ m^2$  

• None of the above

What is the area of the shaded sector?
Recall:  $Area=\frac{\theta}{360}\left(\pi r^2\right)$  

• $108\pi\ in^2$

• $9\pi\ in^2$

• $18\pi\ in^2$

• $216\pi\ in^2$

• None of the above
